A rep for “Castle” confirms that the actress will be in an upcoming episode, which TV Linereports will revolve around the murder of a Sylvester Stallone-like movie star. Allen will play Naomi Duvray, who’s described as “a former silver screen siren who starred in a slew of critically unacclaimed 1980s action movies,” and “the wife of yet-to-be-cast Brock Harmon, the murder vic’s onetime regular costar and now the frontman for a B-movie franchise.”

There’s no word yet on when Allen’s episode will air, but rumor has it that it won’t be long.

“Just booked a fun role on @Castle_ABC,” the actress tweeted last week. “Looking forward to playing with @NathanFillion and @Stana_Katic!”
